An angle-resolved x-ray photoelectron diffraction study of the temperature-dependent surface structure of Pb(100) is performed. Below 550[plus minus]11 K, the decrease in forward-scattered intensity attenuation is exponential with temperature. The intensity attenuation of the forward-scattered peaks is much larger than predicted by both single-scattering and multiple-scattering x-ray photoelectron diffraction models for a bulklike lattice. Corrections for surface relaxation and thermal expansion in the single-scattering cluster model result in an increase in the predicted intensity attenuation; however, sufficient agreement between experiment and calculation is not achieved.
